(In reply to Wei Huang from comment #0) > I saw the following log when boot RHELSA 7.3 kernel (4.4-rc3) as a guest VM > with DT mode. I didn't see this problem when booting it with ACPI mode. Looks like a problem with the guest kernel's DT-boot PCIe host bridge probing. We don't support DT-booting with the RHELSA kernel, so, while it'd be good to resolve it with a rebase someday, in the context of RHELSA, it's not-a-bug. > > NOTE: This could be virt/qemu problem.

The difference is that their kernels are lacking the PCIe host bridge code that induces the backtraces seen with the RHELSA kernel, i.e. pci doesn't work with Fedora guests at all. So can we close this? (In reply to John Feeney from comment #3) > So can we close this? Yup |
